D. A. GREENE WINDOW GLASS GUIDE Filed De c. 24.- 19s4 Patented Jan. 7, 1936 UNITED; STATES PATENT OFFICE I 2,023,911 f f a wmnow (miss some lDanlelA. Greene, FlinhMlch. Application new... 24, 1934, Serial no. 159,020 3cm. (crass-44.5)

This invention relates to guides-for frameless window glass generally employedin automobile bodies, and, more particularly to a type of guide which isadapted to be readily bent 'intocurved formation, to conform to the various curvatures of the window casings when installed. I

The guides of this type which have been most generally employed have usually been provided with a core of sheet metal bent into channel form and having slits, slots, or notches therein which enable the same to be bent without substantial distortion.

As the trade constantly demands decreased manufacturing costs, the primary object of my invention is to provide a guide of the above described character, which will have all the practical advantages of the guides previously employed, but which may be produced at a substantially lower manufacturing cost than has previously been possible.

I accomplish this object primarily by providing a galvanized web of woven wire, having regularly spaced, weft strands and warp strands which are located with special reference to the ultimate use to which it is to be put, then passing the web through a galvanizing bath, then cutting the web into strips suitable to form the channel core, then bending the strips into channel form, and covering the core thus formed with suitable material to which glass cushioning means are attached.

For a more complete disclosure of the inven-,

tion, reference is now made to the following specification in connection with the accompanying drawing in which:

Fig. 1 is a view in side elevationof a preferred embodiment of my invention installed in awindow casing.

Fig. 2 is a detail view of a strip of woven wire material prior to formation into a channel core.

Fig. 8 is a view of a section of the web from which the 'cores are formed. 7

According to my invention, I provide a core for the channel which consists of a strip of woven wire, as indicatedin Fig. 2, said strip comprising a series of regularly spaced transverse, or cross wires in, and a pair of longitudinal or edge wires II, of substantially larger gage than said cross wire I! passes the cross wires at opposite sides thereof successively.

A pair of stay wires are also interwoven with a the crosswires closely adjacent the edge wires l2, the wires of each pair beingarranged to pass at opposite sides of the alternate cross wires in opposite relation to each other, so that each cross 1 wire is held by the stay wires against sidewise movement adjacent the edge wires l2. The entire strip is also galvanized so that all wires which come in contact with one another are practically soldered, or welded together at their points of 15 contact, as indicated in Figs. 2 and 3. It will be understood that, while, as a matter of expense, a galvanizing operation is preferable, a soldering or a spot welding operation is considered as an equivalent. v

In practice a woven wire web is formed in a machine resembling a loom 'in'which the warp strands are the wires l2 and I4 and the weft strands the wires ill, the warp strands l2 and I4 being definitely arranged for the purpose, as indicated in Fig. 8, so that when the weft strands are cut on the lines A, B, C, the strips, such as shown in Fig. 2, will be formed. The galvanizing operation is performed on the web before it is cut into strips.

The strips are then bent into channel form, as indicated in Fig. 7, and the core thus formed being covered with sheet material such as cloth, or sheet rubber L5, to which cushioning material [6 is attached, which will be located within the channel in position to engage the sides and edge of the glass plate which will be placed therein.

Metal finish beads l8 are then clamped about the edges wires I! over the covering IS, the diameter of the wires l2 being sufilcient to enable the beads to be securely attached, so that the finished channel, or guide, is produced, as shown in As the edge wires and beads are located at the extreme edges of the channel, and the stay wires 45 H are located closely adjacent thereto, when the channel is bent to conform to a window casing, as shown in Fig. 1, there will be no longitudinal strain on the edge wires and bead and practically none on the stay wires. There will be a slight strain on the covering, but, as this is of somewhat yieldable material, it will not substantially impede the bending operation, and the cross wires III will merely be swung apart slightly, as will be obvious, so that the bending operation may be 66 Itwillbeunderstoodthatwhilethebeads u will generally be employed, they are not essential to the invention, as they may be omitted it a substantial reduction in cost is desired, also that the location of the stay wires shown is not essential ii'the channelis nottobebentintocurvedfoa'm when installed.
